nvxPRovENmNT IN nUMPING-CARS.

, The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom it {ma/y concern Be it knomi that I, CHARLES GATES, ofBurlington, in the county of Rush, and in the State of Indiana, haveinvented an Improved Automatic Gar-Platform; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters andiigures of reference marked thereon.

The nature of the invention consists in the construction and use o f theautomatic car-platform, hereinafter described, and the construction anduse ofthe devices, hereinafter described, for operating the same, saiddevice. to be made of wood, iron, and leather, or any other suitable andconvenient u iaterials.

To enable others skilled iu the art to make and use my said invention, Iproceed to describe it more fully, as follows:

Figure No. 1,.of the accompanying drawing, is a perspective view .ofvsaid platform.

Figure 2, a transverse section of the same.

Figure 3, a plan of the running-gears ofthe car on which the platform isto be used. v

Figure 4, detailed plan of the rack and pinion used for operating saidplatform. 4

On the axles of the car, at P of fig. 3,- .are bevelgear wheels, which,being free to slip a littleare o1,- eiated by theA lever G" G, which isitselfv moved by the lever G G of fig. l, being attached to it, at G.

These wheels' P and P gear into two corresponding bevel-wheels,represented by N.

The. axles .of N and` N are vertical, and pass u through the timbers,into the pinion N 'of iig. 4, which, with the racks M M, lies directlyunder the cover of the platform, one at each end. l

This cover is jointed at B, B, B, aud B of figs. 1 and 2, and parts atthe line A A'. v v

The two uprights A A', C G are hinged, at C C', so that they can be, ifit be desired, laid down, and the car-top left clear.

Underneath the platform are two (2) strips of leather or other suitablematerials, .one at each end, represented by K K' of said iig. 2. To'thisare attached the segments, which make up the platform, asrepresented by B, B, B, and B, and K K, of said fig. 2.

The .rack M M is attached, at M', to-the platform A, B, B, and B, asrepresented by the appropriate letvters in said g. 2.

To use my said invention as a sand-car, or for any otherA similarpurpose, 'the uprights A A', C C are raised, as ,represented in saidiig. l, and the car loaded in the usual way.

When the car has reached its destination, and it is desired'to unloadit,` just before it stops, the lever Sr" G is oscillated by means ofhandle G G', so that it will throw the bevel-wheels P and P and N and Nin gear. This will revolve the pinion", and move the rack A M M', which,being attached to the platform, will push it out from the middle of the'car. As it moves-out, it will bend down o ver the roller E. E', at thejoints B, B, and B, and so deliver its load on each side of the car.

lVhen the platform has been pushed out far enough to unload thecar, therack and the pinion will be out of gear, and theear' will be iee to movevon.'

A convenient springis placed, so that when the car is backed, and themotion ofthe pinion is reversed, it vn'll again throw the rac-k intogear. Its motiouwill also be reversed, aud the sides A A', C O'bronghtvtogether in the middle of the' car again. The wheels P and P maythen bethrown out of gear by means of the lever G'Gpand G" G', when theear will be ready to reload.

What I claim, and desire to secure by Letters Patent, is-

The dumping-car herein described, when the same is constructed, in itssaid several parts, as aforesaid,

with the jointed platform B B, the levers G G and.

G the rack .M M', and the pinion N, and the 'bevel-wheels N and P, andused for the purpose and in the way substantially as herein' set forth.

In testimony that I claim the foregoing'speciiication, I have hereuntoset my hand, this 2d day of Febru- CHARLES Wanne, Guo. W. Jessen.A
